Industrial businesses often have remote, offsite facilities where materials are stored or processed in some manner. Various transportation modes (e.g., railroad cars, tank trucks, barges, tanker ships) move and store bulk materials for customers. While sen- sors exist to measure level, flow, and other parame- ters of the material, integrated, real-time reporting of the data to a central location from these remote sites often is lacking. Integrating instruments with cellular modems, GPS receivers, and even data secu- rity devices makes it possible to collect and main- tain current inventory status at remote and some- times mobile sites. Using satellite based global communications system, inventories can be tracked and monitored around the world.
